The circuit involves two ideal cells connected to a `1 mu F` capacitor via a key K. Initially the key K is in position 1 and the capacitor is charged fully by 2V cell. The key is then pushed to position 2. Column I gives physical quantities involving the circuit after the key is pushed from position 1. Column II gives corresponding results. Match the statements in Column I with the corresponding values in Column II.

`{:(" Column I ",,,"Column II"),("(A) The net charge crossing the 4 volt cell in "mu"C is",,,"(p) 2"),("(B) The magnitude of work done by 4 Volt cell in " mu "J is",,,"(q) 6"),("(C) The gain in potential energy of capacitor in " mu "J is ",,,"(r) 8"),("(D) The net heat produced in circuit in " mu"J is ",,,"(s) 16"):}`

Answer

(A)-p ; (B) -r ; (C) -q ; (D) -p
